I have a beautiful (that's at least what I think) piece of code that
soft-links to jvm.dll so that a JavaVM instance is created from C++.
The problem is that JNI_CreateJavaVM never returns! Would anyone have
some pointers to let me know what may be wrong in my code?

While referring to the code bellow, dEntryPoint2 is obtained
successfuly from the Dll, it is called, but stays into an infinite loop
(never comes back).

#include <jni.h>

JavaVM *CJavascript::m_JavaVM = NULL;
jclass CJavascript::m_class;
vector<CJavascript*> g_allObjects;
int gProcessCount = 0;

typedef jint (JNICALL JNI_GetCreatedJavaVMs_t)(JavaVM **, jsize,
jsize*);
typedef jint (JNICALL JNI_CreateJavaVM_t)(JavaVM **pvm, void **penv,
void *args);
